Poly-D-Aspartic Acid, Sodium Salt

Poly-D-Aspartic Acid, Sodium salt is a high-purity, water-soluble anionic polymer used in pharmaceutical, biomedical, and industrial applications for its chelating, dispersing, and bioactive properties. As the Sodium salt of a synthetic poly(amino acid), it offers excellent solubility, biocompatibility, and stability, making it suitable for controlled-release systems, tissue engineering, and metal ion sequestration. Poly-D-Aspartic Acid, Sodium salt

• Is a water-soluble, anionic polymer with chelating and dispersing capabilities
• Is used in drug delivery systems, biomaterials, and as a stabilizer for metal ions
• Supports controlled release, bioadhesion, and biocompatible formulations
• Is compatible with aqueous and polymer-based systems
• Is manufactured under Good Manufacturing Practice (GMP) conditions
• Is supplied with complete regulatory documentation including Certificate of Analysis (CoA) and technical data

Poly-D-Aspartic Acid, Sodium Salt is synthesized through polymerization of D-Aspartic acid monomers followed by neutralization with sodium hydroxide. Its polyanionic structure allows for strong interactions with cationic molecules, improving solubility, stability, and bioavailability of associated compounds.

In pharmaceutical and biomedical applications, Poly-D-Aspartic Acid, Sodium salt is used in:

• Controlled-release oral and injectable formulations for small molecules and peptides
• Hydrogels and scaffolds in tissue engineering and regenerative medicine
• Metal ion chelation in formulations containing divalent and trivalent cations
• Ophthalmic and topical formulations for stabilization and bioadhesion
• Cosmetic and nutraceutical applications for moisture retention and active delivery

The polymer exhibits excellent biocompatibility, biodegradability, and minimal cytotoxicity, making it well suited for medical and food-grade applications. Its polyanionic nature also contributes to enhanced solubility of hydrophobic actives and improved viscosity control in aqueous formulations.

CarboMer supplies Poly-D-Aspartic Acid, Sodium salt with precise control over molecular weight, polydispersity, sodium content, and residual monomers.
